Hi there,

I have a spreadsheet containing data representing a 3 dimensional data
structure in the following form;
Z1 Z2 Z3 Z4 ...
Y1 X1 X1 X1 X1
Y1 X2 X2 X2 X2
Y1 X3 X3 X3 X3
Y1 X4 X4 X4 X4
Y2 X1 X1 X1 X1
Y2 X2 X2 X2 X2
Y2 X3 X3 X3 X3
Y2 X4 X4 X4 X4
Y3 X1 X1 X1 X1
Y3 X2 X2 X2 X2
Y3 X3 X3 X3 X3
Y3 X4 X4 X4 X4
.... ....
and so on
In other words for every value Y (of which there are 8800 in total) there
are four X values and I have one set of data (8800 x 4) per month (with nine
years of data in total), so 3,801,600 data items in total (8800 x 4 x 12 x
9)

What I would like to do is average the four X values for each value of Y and
re-display it on a new sheet something like...
Z1 Z2 Z3 Z4 ...
Y1 Xm Xm Xm Xm ...
Y2 Xm Xm Xm Xm ...
Y3 Xm Xm Xm Xm ...
Y4 Xm Xm Xm Xm ...
..... ... ... and so on

However, when I construct the first line of the new file and then try to
drag it I don't get the right results i.e. if the first value of Xm is given
by AVERAGE(B1:B4) and the second is given AVERAGE(B5:B8), I actually get
AVERAGE(B2:B5). Even when I construct the first two lines of the file and
drag it I still don't get the right answer. How can I achieve this simple
action without having to resort to VBA? I'm sure I'm missing something
really obvious, so if I'm being a total noob please tell me :-)

Thanks in advance
Ian

Ok,

Original data is in sheet1, condensed data on sheet2...
Cell A1 on sheet2 contains a reference number carried forward from sheet1
Cell B1 on sheet2 contains the formula =AVERAGE(Sheet1!C2:C5)
Cell C1 on sheet2 contains the formula =AVERAGE(Sheet1!D2:D5)
Cell D1 on sheet2 contains the formula =AVERAGE(Sheet1!E2:E5)
and so on...
Cell B2 on sheet2 should have the formula =AVERAGE(Sheet1!C6:C9)
Cell C2 on sheet2 should have the formula =AVERAGE(Sheet1!D6:D9)
Cell D2 on sheet2 should have the formula =AVERAGE(Sheet1!E6:E9)
but actually reads (when cells in row 1 dragged to fill the cells below)...
Cell B2 on sheet2 sactually reads the formula =AVERAGE(Sheet1!C3:C6)
Cell C2 on sheet2 sactually reads the formula =AVERAGE(Sheet1!D3:D6)
Cell D2 on sheet2 sactually reads the formula =AVERAGE(Sheet1!E3:E6)

In B1 on sheet2

=AVERAGE(INDIRECT("Sheet1!C"&ROW(H$2)+4*(ROW(H1)-1)&":C"&ROW(H$2)+4*(ROW(H1)-1)+3))

In C1

=AVERAGE(INDIRECT("Sheet1!D"&ROW(H$2)+4*(ROW(H1)-1)&":D"&ROW(H$2)+4*(ROW(H1)-1)+3))

etc., copied down

This is an ideal application for Pivot Table.
No formula or code is required.
Assume your data looks like this:
Z1 Z2 Z3 Z4
Y1 27 81 20 55
Y1 39 21 93 23
Y1 75 63 86 37
Y1 82 73 61 22
Y2 43 92 86 24
Y2 67 36 67 64
Y2 44 22 32 96
Y2 31 40 38 91
Y3 91 60 37 17
Y3 19 86 31 37
Y3 35 72 84 88
Y3 76 93 58 27
Data Pivot Table Multiple Consolidation Ranges
Range: Select the above 13 x 5 array
Layout: DATA = Average of Value
Options: Uncheck Grand Totals, AutoFormat
The result will look like this:

Average of Value Column
Row Z1 Z2 Z3 Z4
Y1 55.75 59.50 65.00 34.25
Y2 46.25 47.50 55.75 68.75
Y3 55.25 77.75 52.50 42.25

Month and Year data can be added in
the Range table and shown in PAGE fields.

Thankyou for the solution - it worked a treat.

Thankyou for the solution to my problem which you posted. In the end I went
with the pivot-table solution proposed for me elsewhere. However, I will be
keeping your code in hand for the future.
